The mobile communication terminal preferably performs IP packet communication using Point-to-Point Protocol (PPP).

The base station (BS) 12, 12 'is installed at a fixed position and can simultaneously provide voice and data communication services wirelessly with the mobile communication terminals 11, 11'. The base station (BS) 12, 12 'is connected to the base station controller (BSC) 13, 13' via a dedicated line.

The base station controllers 13 and 13 'control the plurality of base stations 12 and 12' and are responsible for handoff processing and the like of the mobile station. The base station controllers 13 and 13 'are also connected to mobile switching centers (MSCs) 14 and 14' via dedicated lines, and likewise to gateways 17 and 17 'for wireless data services.

The gateways 17 and 17 'are located between a packet data serving node PDSN and a base station controller BSC to provide an interface function for providing a wireless Internet service.

MSCs 14, 14 'are coupled to a public switched telephone network (PSTN). Optionally, a mobile switching center (MSC) can be connected to a packet data serving node (PDSN). The MSC includes a home location register (HLR) 15 and 15 'which stores subscriber information such as the location of the mobile communication terminal and whether to subscribe to a service, and a visitor location register to manage mobile communication terminals existing in the jurisdiction. (VLR) s 16 and 16 'are connected.

A packet data serving node 18 is provided to provide a wireless Internet service. The packet data serving node PDSN and the mobile communication terminal MS perform IP packet communication using a point-to-point protocol, and the packet data serving node performs mobile IP management and registration functions.

The lie detection service server 19 includes a voice analysis function for recording and analyzing the voice of the call counterpart upon request of the caller, and includes a message transmission function for providing the analyzed result to the caller or the called party.

A method of providing a lie detection service in a network having the above configuration will be described in detail with reference to FIG. 2.

First, the calling subscriber enters the telephone number of the called party using the mobile communication terminal (MS) and presses the SEND key, so that the call setup request is sent via the base station BS and the base station controller BSC. Is passed to. The procedure according to the call establishment request follows the well-known IS-95 standard.

When the originating mobile exchange receives the call establishment request from the mobile communication terminal of the originating subscriber, it checks whether the originating subscriber is a lie detection service subscriber (101, 102). If the calling subscriber is not the lying detection service subscriber, general call processing is performed (103). If the calling subscriber is a service subscriber, the call is set up via the lie detection server (104).

The calling party mobile exchange transmits the telephone number of the called party included in the call setup request message to the home location register (HLR) that manages the information of the called party. Query When the originating mobile exchange receives a response to the query from the home location register, it requests a call setup to the called party mobile exchange to which the called party belongs. At this time, the calling mobile switching center establishes a call with the called mobile switching center through the service server. The called party mobile exchange calls the called mobile communication terminal when a call is established with the calling mobile exchange. Through this process, the calling mobile communication terminal and the called mobile communication terminal are in a call state (105).

On the other hand, in order for the calling subscriber to be provided with the service, it must be a subscriber of SVD service. The originating mobile switching center (MSC) is connected between the mobile communication terminal and the packet data serving node (PDSN) to connect the service server and the originating subscriber's mobile terminal (MSC) to the base station controller (BSC) when the originating subscriber is an SVD subscriber. Require a point-to-point protocol connection.

The base station controller (BSC) sets up the data channel with the base station (BS) for the point-to-point protocol (PPP) setting between the mobile subscriber station (MS) of the calling subscriber and the packet data serving node (PDSN) at the request of the calling mobile switching center. Require. At the same time, it also requires circuit establishment between the base station controller and the packet data serving node (PDSN).

The base station BS establishes a data channel with the mobile communication terminal. In this regard, a Fundamental Channel (FCH) is established between the child communication terminal and the base station to establish a voice call. The basic channel includes a signaling channel as well as a traffic channel. The base station requests the establishment of a supplemental channel (SCH), which is a data burst channel, using the signaling channel of the base channel. Accordingly, a basic channel for voice service and an auxiliary channel for data service are established between the mobile communication terminal and the base station. Meanwhile, in setting the data channel, the base station requests setting of an auxiliary channel (SCH) for data transmission to the mobile communication terminal using a forward dedicated control channel (DCCH), and thus the mobile communication terminal and the base station The primary channel for voice service and the secondary channel for data service may be set.

Through the above process, a channel for data service is established between the mobile communication terminal and the base station controller, and a session is established between the base station controller and the packet data serving node PDSN (210, 211). In this way, when the circuit setting is completed, the PPP connection is started between the mobile communication terminal and the packet data serving node, and the mobile IP for packet communication is registered.

Through this process, a call state is established between the calling subscriber and the called subscriber, and a session is started between the calling terminal's mobile communication terminal and the service server of the present invention. In this state, when the calling subscriber instructs to start the lie detection to check the authenticity of the called subscriber (106), the lying detection server records the voice of the called subscriber and analyzes the recorded voice using a conventional analysis algorithm ( 107). Then, the analyzed result is transmitted to the mobile communication terminal of the calling subscriber using the already established data channel (108). The originating mobile communication terminal graphically displays the analysis result sent from the lie detection service server on the display.

Meanwhile, the called party may request the authenticity analysis data from the calling party during the call between the calling party and the called party. In this case, the calling subscriber requests the service server to provide the voice analysis result to the called subscriber. In this case, the voice analysis result may be a voice analysis result of the called party or a voice analysis result of the calling party.

When the calling subscriber requests the service server to notify the called subscriber of the voice analysis result at the request of the called subscriber, the service server checks through the home location register whether the called subscriber is an SVD subscriber (109, 110). ). If the called subscriber is an SVD subscriber, the service server transmits the voice analysis result to the called subscriber mobile communication terminal through a data channel already established between the called subscriber and the service server (111). However, if the called subscriber is not the SVD subscriber, the service server provides the voice analysis result data to the short service center (SMSC) (112). Accordingly, the voice analysis result is provided from the short message center to the mobile communication terminal of the called subscriber in the form of a short message.

Thereafter, when the call is terminated between the calling party and the called party (113), a procedure of releasing the call is performed (114).

While the content of the present invention has been described by way of examples, the embodiments of the present invention are merely illustrative of the present invention and should not be construed as limiting the scope of the present invention. Those skilled in the art to which the present invention pertains may modify or alter the present invention in various forms within the principles and scope described in the claims herein.

According to the present invention as described above, the calling party and the called party can check the authenticity of the other party's words while talking on the server, it can be confirmed immediately.
